Thank you, I get the sense that you're not trying to be overly negative. But I'm also slightly confused. If you can't gain credibility with valid arguments and research, how else can you?
The article as is right now, won't be shared as much as could have been if it had objective tone. What I've seen a lot of people do is make a useful and objective argument about what the message they're trying to convey and then maybe at the end mention their message briefly. That's how people build credibility. Check out all "Crunch Network" posts on TechCrunch. Even though most of the writers behind those articles do have agenda (they all have some stakes in the subject matter), a lot of those articles are useful. Since the content is useful, a lot of people share them and there's no lost credibility.
